Abstract

Process for producing a composite material comprising depositing a prepreg containing a radiation initiated curing agent onto a mould using automated apparatus and applying heat and second source radiation to at least partially cure the prepreg at least simultaneously with the deposition of the prepreg. Also epoxy resin formulations of a mixture of a liquid epoxy resin and a solid or semi-solid epoxy resin containing a photoinitiator are used as the matrix in prepregs which are cured or partially cured by radiation to avoid the need for thermal cure in an oven. The formulation is particularly useful in the production of wind turbine blades especially in an automated process. Additionally an automated tape laying apparatus comprising compaction device, a heat source and a second radiation source.
